Objective To explore the influence of combination of Chinese traditional and western medicine continuing nursing care on treatment outcome and quality of life of patients with chronic urticaria.Methods 96 confirmed chronic urticaria patients were selected and divided into the control group and the observation group with 48 patients in each group according to random digit table.The control group was given with routine nursing mode.The observation group received combination of Chinese traditional and western medicine continuing nursing care.The treatment lasted for 12 months.Treatment effect and Dermatology Life Qudity Index (DLQI) evaluation were executed at the end of the 3rd,6th and 12th months.The relapse was inquired 2 months after the intervention by follow-up.Results The total effective rates in the control group and the observation group at the end of the 3rd,6th and 12th months were 75.6％ (34/45),80.0％ (36/45),82.2％ (37/45) and 87.0％ (40/46),91.3％ (42/46),93.5％ (43/46),the results showed significant difference,P ＜ 0.05.DLQI scores at the end of the 3rd,6th and 12th months in the control group and the observation group were (7.82±1.95),(7.04±1.58),(6.56±0.88) scores and (6.85±1.56),(5.71±1.03),(3.42±0.78) scores,the differences were significant,P＜0.05.The relapse interval time was (24.75±5.07) days and (38.20±7.22) days,the difference was statistically significant (P＜0.01).Conclusions Combination of Chinese traditional and western medicine continuing nursing care can significantly improve treatment outcome of chronic urticaria,reduce relapse rate,increase quality of life for patients with chronic urticaria,and it is better than routine nursing care and is worthy of being popularized.

Objective:To detect the serum level of chitinase-3-like protein 1 (YKL-40) in patients with pemphigus vulgaris, and to analyze its correlation with the severity of pemphigus vulgaris.Methods:From January 2017 to May 2018, serum samples were collected from 38 patients with pemphigus vulgaris in Department of Dermatology, the Affiliated Hospital of Southwest Medical University, and those collected from 14 age-, gender- and body mass index-matched healthy volunteers served as controls. Serum levels of YKL-40 and Th1/Th2/Th17-related cytokines were detected by using Luminex ? 200 TM system. Mann-Whitney U test was used to compare serum levels of cytokines between the patient group and control group; binary logistic regression was used to investigate factors independently related to the severity of pemphigus vulgaris; a receiver operating characteristic (ROC) curve was drawn, and the area under the curve, sensitivity and specificity were calculated to evaluate the ability of YKL-40 to predict the severity of pemphigus vulgaris. Results:Compared with the control group, the patient group showed significantly increased serum levels of YKL-40 (expressed as median[ Q1, Q3]: 15.22 [14.19, 15.93] vs. 13.64 [13.21, 14.63]μg/L, z=-3.88, P < 0.05) , interleukin (IL) -6 (2.05 [1.49, 4.21] vs. 1.57[1.38, 1.75]ng/L, z=-2.44, P < 0.05) , IL-7 (7.45[5.63, 11.63] vs. 3.77[2.21, 5.97]ng/L, z=-3.26, P < 0.05], IL-8 (6.59[3.60, 14.73] vs. 4.36[2.96, 6.53]ng/L, z=-1.96, P < 0.05) , IL-2R-α (509.08 [386.36, 757.67] vs. 336.44[309.86, 458.71]ng/L, z=-2.35, P < 0.05) , and C5a (100.35 [78.31, 140.84] vs. 72.08 [37.23, 82.08] ng/L, z = -3.04, P < 0.05) . The concentration of serum YKL-40 gradually decreased along with the reduction of lesion areas ( r = 0.63, P < 0.001) , and YKL-40 was independently correlated with the severity of pemphigus vulgaris ( P = 0.025, OR = 46.54, 95% CI: 1.61, 1 347.19) . The area under the curve of YKL-40 was 0.783 (95% CI: 0.613, 0.953) for distinguishing between patients with severe to extremely severe pemphigus vulgaris and those with mild to moderate pemphigus vulgaris. Conclusion:The serum level of YKL-40 is strongly correlated with the severity of pemphigus vulgaris, and has a potential value in predicting the severity of this disease.

Background: The gut microbial dysbiosis and gender differences in the pathogenesis of acne vulgaris have long been postulated respectively. However, there was no data about a genderrelated discrepancy in gut microbiota and microbial metabolism in acne. Objective: This study aimed at identifying the underlying gender-related difference in gut microbiota and metabolism in acne vulgaris. Methods: Fecal samples were collected from 43 acne patients and 43 age and gender-matched controls. Gut microbiota was analyzed by sequencing the V3-V4 region of 16SrDNA gene and microbial metabolites were quantitatively detected using gas chromatography time-of-flight mass spectrometry. Results: Compared with healthy controls, the men had a lower abundance of 18 microbes such as Butyricicoccus, Clostridium sensu stricto, Faecalibaculum, Bacillus, Lactococcus, Blautia, Clostridiales, Lachnospiracea incertae sedis, Ruminococcus at genus level. However, the female patients only showed increased Clostridium sensu stricto and declined Oscillibacter and Odoribacterin. Additionally, the disordered metabolism of fatty acids was identified in male patients, while the dysbiosis of amino acids metabolism in female ones. Conclusion The disorder of gut microbiota and metabolism in acne vulgaris was genderspecific, which supported the potential role of gender difference in the pathogenesis of this disease.

Objective To analyze the levels of IgE,TNF-α and FeNO in children with acute attack of bronchial asthma and their correlation with the severity of bronchial asthma, so as to provide theoretical basis for clinical evaluation of bronchial asthma. Methods A total of 547 children with acute bronchial asthma treated in Chengdu Women and Children's Central Hospital from January 2020 to December 2020 were selected and divided into mild group (n=287), moderate group (n=186) and severe group (n=74) according to the severity of their disease. All the children's symptoms were controlled after treatment. The serum IgE, TNF-α and FeNO levels in the experimental group were compared between the acute attack stage and the clinical control stage. Spearman correlation analysis was used to analyze the correlation between the serum IgE, TNF-α and FeNO levels and the severity of the disease. ROC curve of children with bronchial asthma was drawn to analyze the differential diagnosis value of serum IgE, TNF-α and FeNO levels in children with acute bronchial asthma. Results The levels of IgE, TNF-α and FeNO in acute stage were significantly higher than those in clinical control stage (P<0.05). The levels of serum IgE, TNF-α and FeNO in severe group were higher than those in mild and moderate groups significantly (P<0.05). The levels of serum IgE, TNF-α and FeNO in moderate group were higher than those in mild group significantly (P<0.05). Spearman correlation analysis showed that serum IgE, TNF-α and FeNO water were positively correlated with the severity of bronchial asthma (r=0.419 , 0.438 , 0.502 , P<0.05). ROC curve analysis showed that the AUC, sensitivity, accuracy and specificity of serum IgE, TNF-α and FeNO levels combined in diagnosing the severity of bronchial asthma in patients with acute attack was 0.938 (95% CI: 0.912-0.982 ), 83.47%, 92.06%, 94.28%. Conclusion The level of serum IgE, TNF-α and FeNO in children with acute attack of bronchial asthma is closely related to the severity of the disease, and combined detection of the three can be used to evaluate the severity of the disease in children.
